Product Description:

 

The operation of a photovoltaic (PV) cell requires 3 basic attributes:

 

The absorption of light, generating either electron-hole pairs or excitons.

The separation of charge carriers of opposite types.

The separate extraction of those carriers to an external circuit.

In contrast, a solar thermal collector supplies heat by absorbing sunlight, for the purpose of either direct heating or indirect electrical power generation from heat. A "photoelectrolytic cell" (photoelectrochemical cell), on the other hand, refers either to a type of photovoltaic cell (like that developed by Edmond Becquerel and modern dye-sensitized solar cells), or to a device that splits water directly into hydrogen and oxygen using only solar illumination.Characteristic of Mono 156X156MM2 Solar Cells

You are gaining energy independence - add battery backup power for even greater energy security

The cost of electricity is only going to rise – insure against that rising cost

Adaptive cells change their absorption/reflection characteristics depending to respond to environmental conditions. An adaptive material responds to the intensity and angle of incident light. At the part of the cell where the light is most intense, the cell surface changes from reflective to adaptive, allowing the light to penetrate the cell. The other parts of the cell remain reflective increasing the retention of the absorbed light within the cell.[67]

 

In 2014 a system that combined an adaptive surface with a glass substrate that redirect the absorbed to a light absorber on the edges of the sheet. The system also included an array of fixed lenses/mirrors to concentrate light onto the adaptive surface. As the day continues, the concentrated light moves along the surface of the cell. That surface switches from reflective to adaptive when the light is most concentrated and back to reflective after the light moves along

Poly solar cell 156mm manufacturing process
Cell sorting - Single Welding - string jointing - splicing (the string is welded battery slice positioning, stitching together) - intermediate test (intermediate test points: Infrared testing and visual inspection) - laminated - cutting edge - layer after appearance - after layer infrared - mounted box (usually aluminum frame) - mounted terminal box - cleaning - tests (this link also points infrared testing and visual inspection of the component level determination.) - Packaging.
(1) poly solar cell 156mm test
Because of the randomness of the solar cell manufacturing conditions, produced by the battery performance is different, so in order to effectively identical or similar battery together, it should be classified according to its performance parameters; battery test through the test cell output parameters (current and voltage) of the size of its classification. In order to improve the utilization of the battery, a battery pack made of acceptable quality.
(2) poly solar cell 156mm welding positive
Main gate line, convergence with soldered to the battery positive (negative), the convergence zone for the tinned copper strip, we use a welding machine can weld with a multi-point spot welding in the form of the main gate line. Welding heat source is an infrared lamp (using infrared thermal effect). The length of the ribbon is about 2 times the battery side length. More welding belt behind the back of the welding electrode is connected to the back of the back of the battery slice.
(3) poly solar cell 156mm in series
On the back of the battery is soldered together in series to form a module string, we are currently used process is manual, locate the battery depends mainly on a membrane with plate placement battery film grooves, groove size and battery size phase corresponding to the location of tank has been designed well, different specifications of the components use a different template, the operator use a soldering iron and solder wire will "in front of the battery," the positive electrode (anode) is welded to the "behind the battery" on the back electrode (cathode) this in turn connected in series with the positive and negative components in a string of welding wire.

Q:How can I understand the working principles of solar cells?
My way of understand the working principles of solar cells is to read tons of books about that topic.
Q:Anybody ever heard of solar roll flexible solar panel?
The flexible solar cell rolls is more convenient than the other solar cells because it can be stored in a convenient storage tube.
Q:How can the solar power change our life by using solar cells material?
Solar power is at least 1/3 less expensive than coal-fired power . How can not the solar energy be used to change our life?
Q:I would like to use a ppt to show how solar cells can work in a power generation factory, can anybody share some useful information with me?
The idea behind solar cells is we basically using the free electricity from the sun.
Q:Is it possible to learn how to make solar cells by yourself?
I don't know how to make a solar cell by myself, but I am very interested in your trying to do it.
Q:Where can I buy the 156x156mm high efficiency poly solar cells assembly?
It is not difficult to buy the 156x156mm high efficiency poly solar cells assembly,but the only concern would be the quality.
Q:Why should the solar cells be laserized?
While the P2, P3 level with green nano-laser is the most ideal. In the actual experiment process using green picosecond laser technology the best, but taking into account the cost of equipment into the point of view, green nanosecond most ideal
Q:How long is the long cycle solar cell life?
There are charging conditions, if often less than filling, charge less than the release, then it will soon be "broken", a single cycle of the amount of charge should be more than 1.2 times the discharge
Q:What is the internal structure of solar panels
3) The main role of the battery is the power generation, power generation main market is the mainstream of crystalline silicon solar cells, thin film solar cells, both of their advantages and disadvantages.
Q:How to make solar cells in a scientific way?
Follow the scientific instructions, then you will learn how to make it.
